Thermal Performance Testing

To simulate thermal demand, we run the Cinebench R23 multi-thread benchmark and 3DMark Speed Way stress test simultaneously in a loop for 30 minutes to load the system fully. This gives the CPU and GPU enough time to reach constant steady-state temperature. With this data, we can compare how the system handles the thermal demand and measure peak noise levels.

Thermal performance is measured with the case in various configurations, such as the default, with the tempered glass left-hand side panel removed and with the front panel removed to see how these configurations affect the CPU and GPU temperature. During testing, only stock case fans are used unless otherwise specified. All water pumps are set to maximum RPM and fans are set to a custom RPM curve by the Motherboard software/BIOS.

All temperature measurements are presented as Deltas – meaning the ambient temperature has been deducted from the CPU temperature, giving us a Delta. Data shown in the charts represents the average component temperature over the length of the test as measured by HWiNFO, and then the last 15 minutes of the data are calculated to get the average. The ambient temperature during thermal tests is between 19-20⁰C.

Thermal Performance Overview

We test case thermals using a 360mm AIO as exhaust at the top and with the case in several different fan configurations. The default configuration shown in the charts is with the top 360mm AIO cooler, 2 x 200m front intake fans, a single 120mm rear exhaust fan and with all case panels installed.

Thermal performance from the Cougar MX600 Max is very impressive overall. In its default configuration the case keeps both the CPU and GPU temperature under control at 55°C over ambient, showing that the pre-installed airflow setup is well optimised.

Removing the front and top panels and dust filters, produces no meaningful improvement, which tells us those panels cause very little restriction to airflow. The biggest improvement however, comes from fitting optional floor intake fans which reduce GPU temperature by 3°C compared to the default setup, while maintaining the same CPU temperature. This setup is ideal for optimising GPU performance.

Noise Output

Noise performance from the Cougar MX600 Max is also quite impressive. In its default configuration, the system reaches 47dBA under full load, which is a reasonable result given the large 200mm front intake fans and included cooling setup. Interestingly, removing the tempered glass side panel and adding floor intake drops noise output by 3dBA to 44dBA,  showing that the extra GPU cooling also reduces GPU fan speed and noise.

Removing the front panel, along with the front and top dust filter makes no difference to noise levels compared with the default setup, which shows that Cougar has done a good job optimising airflow through the chassis. The only configuration that increases noise is removing the front air scoop and adding side intake fans, which raises noise output to 49 dBA while offering no real thermal advantage.

Closing Thoughts

The Cougar MX600 Max is a very easy case to recommend. It does exactly what its design to do, offering high airflow and extensive hardware compatibility without overcomplicating the design. The pair of pre-installed 200mm PWM ARGB intake fans, combined with the mesh front panel, provide excellent cooling performance straight out of the box. There's very little to be gained from removing panels or filters, which indicates that Cougar has optimised the airflow well. If you're looking to optimise GPU cooling, fitting PSU shroud intake fans can knock a few degrees from GPU temperatures, but the gains are relatively small as the default cooling setup is already effective.

Hardware compatibility is another strong point. It supports graphics cards up to 400mm long, 360mm radiators in the roof, tall air coolers, back-connect motherboards and loads of 2.5” storage, so there's very little this case won't accommodate. Building inside the MX600 Max is straightforward too; there's loads of space to work, generous cable-routing cut-outs, plenty of clearance behind the motherboard tray and integrated Velcro straps helping to keep cables managed and looking tidy. The overall build quality is solid throughout which gives the MX600 Max a premium feel despite its competitive pricing.

There are only a couple of minor negative points to consider before buying. The first is the size of the chassis, it is a mid-tower, but feels bulky compared with some ATX cases that offer similar hardware support. It may not be ideal in terms of size to run it on a desktop space. The second is radiator support at the front of the case. Cougar has prioritised the large 200mm intake fans, which means there's no option to install a front-mounted radiator. For most users this won't matter, particularly given the excellent top-mounted 360mm radiator support, but it does reduce options for custom cooling.

Overall, the Cougar MX600 Max is an excellent airflow-focused chassis that gets the basics right. It combines solid thermal performance, sensible acoustics, good hardware compatibility, an easy building experience and great build quality with a sensible MSRP. Unless you specifically need front radiator support or a more compact chassis, the MX600 Max is easy to recommend and deserves to be considered alongside some of the best airflow cases in its price bracket.

Pros: 

• Lots of space to work with.
• Great thermals and low noise.
• Included fan/rgb hub.
• Good price.

Cons:

• A little large for a mid tower.
• No front radiator support.

KitGuru says: Unless you specifically need front radiator support or more compact dimensions, the Cougar MX600 Max is a serious contender if you're looking for a well-built, high-airflow chassis.
